To aZZ whom it 17mg concern.-

Be it known that we, BENJAMIN F. DETTRA and GEORGE R. ROTH, of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful In:- provementsin *indows; and we do hereby declare the following to be afull, clear, and exact description of the invention, such. as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in windows, and more particularly to a type in which the upper and lower sash are supported by weights to hold them counterbalanced at any point of elevation or lowered adjustment; of the same.

The primary object of our invention is to construct the frame and sash of a window so that the sash willeach be countel-balanced to maintain them at any point of sliding vertical adjustment, and also permit them to be swung outwardly while they. are held in hinged contact at their meeting-rails, and be adjusted at any desired angle withregard to each other and the window-frame for purpose of ventilation.

A further object is toprovide a window with sash-locks whiehwill secure the upper and lower sashes to-the frame as well as together. at their meeting-rails, and thus atford a secure lock to the sash.

A further object is to so connect the upper and lower sashes to two counterbalanceweights that one pair of such weights of proper heft will answer for the counterpoise of both the upper and lower sashes.

A further object is to provide a window with sash so constructed and arranged that the upper sash may be projected outwardly at an angle to the frame, and, being covered with a removable fabric, answer as an awning or screen to protect the window from the rays of the sun,while the lower sash is free to be raised or lowered, as occasion may require.

Vith these objects in view our invention consists in certain novel features of construction and peculiar combinations and arrange ments of parts as will be hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of awindow frame and sash embodying our invention. Fig. is a side elevation in section of a window frame and sash. Fig. 3 is a side elevation in section of the window frame and sash with the latter in 5 5 closed and locked position. Fig. l. is a plan view in section of the window frame and sash, taken on the broken line y 11 Fig. orabove the sash-locks, showing the locks in perspective and the ends of their locking-bolts in section where they pass through the sash-frame. Fig. 5 is an enlarged plan view of one of the sash-locks. Fig. (5 is longitudinal elevation in section of the portion of the sash-lock which is secured to the meeting-rail of the upper sash. Fig. 7 is a side elevation of thcwindowframe with the window-sash adjusted to project the upper sash as an awning, the lower sash being in closed adjustment. Fig. 8 is a side view of an upper corner of the upper sash broken away to expose the cord-clamp, which is shown in section with a sash-cord in clamped position. Fi 9 is a side view of a lower corner of the lower sash in section as well as a cord-clamp with sash-cord in clamped 7 5 position. Fig. 10 is an end view of the lock. Figalil is a view of a portion of a window frame with portions of the sash in place therein, showing a plan. of arrangement for counterbalancing the upper and lower sash with a singlep'airol? weights. 12 isadctached enlarged front perspective view of the sash-cowl clamp.

A. indicates a wimlow-frame provided with boxes on the sides for the reception of the saslrweights l, constructed in the usual manner. The frame is further constructed with parallel stiles a a and intervening beadstrips 6, which forms channels in whichthe sash-cord 2 may travel as well as the side edges of the sash. The inner stiles, a, project sufficiently to form abutments for the lower sash, 13. The upper half of the bead-strips b are also inwardly extended to engage the upper sash, B, when these sashes are adjusted 5 to slide vertically, as will be further explained.

From the point 0 the bead-strips b are cut away to align their faces with the outer stiles,

a, for a purpose that will be shown. Ioo

Near the lower edge of the lower sash, B, the cord-clamps C are secured on the side faces of the same, the ends of the cord 2 being held firmly connected to the lower sash by the 5 clamps. Thence they are upwardly extended to engage the pulleys 4-, and havetheir other extremities fastened to the weights l by any suitable means.

The cord-clamps (J (shown in Figs. 10, 11,

IO and 12) are alike, so that a description of one will serve for the two pairs employed to secure the cords to the upper and lower sash.

It will be seen that the clamp O is a circular block of metal, and is cut away on the 15 face to produce a channel, (I, in it for the ac commodation of the cord 2, leaving the guardshoulders (Z' (Z stand, these latter serving to retain the cordin the channel. A screw-hole, 5, is formed in the body of the clamp-block 0, near the circular edge of said block below the notch 6, that is cut in the upper edge of the same to receive the sash-cord, and a slim sharpened pin, 7, projected from the rear face of the block 0 is adapted to penetrate the 2 5 saslrcord when .it is adjusted in place on the sash.

The attachment of the cord 2 to the sash B is effected by boring holes the size of the cord in the side faces of the sash near the lower 0 edge a sufficient depth to receive the ends of the cords, which are covered by the clamps C, so that the pins 7 penetrate through. the body of the cord. Screws are now inserted in the sash through the holes 5, which will bind the 3 5 cords securely in connection with the sash.

As the cords 2 are extended into the vertical grooves formed for them between the strips a and the bead-strips b, thence upwardly to engage the pulleys and be con- 0 nected to the sash-weights l, as previously explained, it is evident that the lower sash, B, may be reciprocated vertically, and be supported by the counterbalancing-weights at any desired point, and, as the cord-clamps C 4 5 are round on their edge surface and are of proper diameter to slide neatly within the sash-cord grooves formed by the beadingstrips and the stiles (1, these clamps form trunnions on which the sash may rock out-- wardly to project its upper edge beyond the bead-strips b when the upper edge of'thc sash B is below the offset-shoulder c on said strips.

The upper sash, B, is provided with cordclamps C of a form identically the same as 5 5 those on the lower sash, said clamp-blocks. be-

ing affixed to the side faces of the upper sash at opposite points-near the upper rail ofthe sash, so that the sash-cord may extend'and' engage the grooved top surface of the cordsupporting pulleys and be attached byopposite ends to the sash-weights, which are thus adapted to afford movable support to the upper sash, which may slide downwardly in rubbing-contact with the adjacent faces ofthe bead-strips b, or be swung outwardly, if d'e.-

sired, as the relative width of the sash to the space between the faces of the stiles a will permit it to have an outward rocking movement on the rounded sash-cordclamping plates 0 as trunnions or pivotal centers.

Two duplicate sash-locks, D, are employed and placed on the meetin transverse rails of the upper and lower sash, as shown, the locks each having a slide-bolt, c, which is held in a frame, 6, that is provided with a flanged base-plate, e to permit the frame to be securedupon the meeting-rail of the upper sash, B, the frames with the slide-bolts being located near the opposite side pieces, 13*, of the sash, which pieces are perforated at a proper point to allow the bolts c to move freely in said perforations.

On the sides of the sash-lock frames e which are adjacent to the meeting rail of the lower sash, B, the inverted-T slots 6 are cut through the walls of the frame to receive laterally-projected levers f, which latter are anade of a proper length, and have rounded pintles g formed at their ends that project at a right angle to the bodies of the levers, and are adapted to enter holes made for their reception in earsf, formed on the ends of locking-plates E, secured to the upper surface of the top rail of the lower sash, B, so that the pintles g will be in alignment with the perforations in the ears f. These holes are preferably made sufficiently conical. to admit the rounded ends of the pintles g freely, and yet cause the rails of the upper and lower sash to be drawn together when the pintles are shoved completely in these slightly coneshaped holes.

The locking-plates E are further provided with inverted-L-shaped lugs 71, under the overhanging limbs of which the bodies of the bolt-levers f will slide and be held when the boltsare thrown to lock the upper and lower sash from-being pushed outwardly, and it should be here explained that round flat platesc are loosely secured to revolve on the ends of the bolts 6, said round disks 6* sliding neatly in the groove between the outer stiles and the bead-strips of the windowframe, and being seated in recesses cutin the sash when the bolts are inwardly drawn.

In order to. hold the slide-bolts e of the sash-locks D from rattling and prevent them from improper longitudinal movement in their retaining-cases, an arched plate-spring,- 1, is introduced below each slide-bolt, which springs are bowed upwardly and have yielding cont. ct with the lower surface of the slide-bolts, so that these bolts will be held at airy-desired point of longitudinal. adjustment byv the tension of the springs '2'.

It may be here explained that in order to facilitate manufacture the frames 6 are made in two parts, the upper portion being cut away near its center of length upon the lower side, so as to form an aperture below the inverted- T slots 6 andthus allow the levers f to be int-reduced into said slots. A bottom plate, 6 is secured to theflanges of each base-plate e These close up the holes in the bolt-frames e and form a seat lfor the springs 1', previously mentioned.

In operation the pintles g of the levcrsf, when shoved into the holes in the ears f, produce a hinged connection on the adjacent rails of the upper and lower sash, and it is evident that these sash-frames B 3 may be adj ustcd to project; outwardly at any desired bolts 6, that will cause the disks on the ends of these bolts to engage the sides of the center head, i), and stiles o a, as has already been explained. izc the upper sash, B, as a sun shicld or awning, there may be a removable curtain, (l, secured on the outer surface of said uppersashframe, as shown in Fig. 2, and the two sashes that are held in hinged connection be suf- .ticiently projected at an angle so as to properly incline the upper sash outwardly, thus affording tli'rce ventilation to an apartnnuit, while it is protected from the direct rays of the sun. In case it is preferred to project the upper sash independently of the lower sash,

this may be eii'fectcd by a disconnection of their hingcifl attachment after they have been pushed outward. Then the upper sash may be propped or otherwise secured outwardly at any desired angle and the lower sash be free to slide and be made to assume any position in its rctaimug-grooves. It is obvious that as soon as the upper edge of the lower sash, B, l passes the offset-shoulders c on thebeadstrips b said sash-frame will be engaged by the bead-strips and stile (1, thus holding it from lateral displacement when the lower sash is elevated.

In Fig. 11 a plan of construction is shown in which the upper and lower sash may be suspended and counterbalanced b a single pair of weights. In this view the weight 1 is provided with a grooved pulley, 7., that is attached to a bracketarm on the upper edge of the weight, said pulley engaging a bight in the cord '2, one oi the doubled strands of which cord extends upwardly to pass over a pulley, p, and be attached to the upper portion of the top sash, B, on its side edge. The other strand passes over a similar pulley, p, and thence downwardly, and is secured by its terminal end to the lower sasln Both sides of the window-sash are provided with a single weight, 1, and cord rigged as just described, the attachment of the ends of the cord toi'he upper and lower sash being made with trunnion clamp-bloclcs of the same construction as has been meviously described, so that the sashes, when fitted with the improved sashloeks, as hereinbefore explained, can be rocked outwardly and be held at any desired point of sliding adjustmentby the two counterbalance-weights equally as well as it four weights were used.

Many slight changes might be made in the details ol": construction of this improvement within the scope of our invention. Hence we do not wish to limit ourselves to the exact forms herein shown; but,

Having fully described our lilVOllllOlls, what we claim as new, and desire to secure by Let? ters Patent, is
